Abstract

A shielded electrical connector includes a connector body having contact pieces embedded therein and an “L”-shaped shield plate applied to the connector body with its horizontal and vertical sections lying on the top surface and rear side of the connector body, the shield plate having press-fit portions integrally connected to the lower end of the vertical section. The shield plate has thrust shoulders formed at its horizontal-to-vertical transition for use in pushing the press-fit portions. The electrical connector can be fixed to a printed circuit board by applying a push to the thrust shoulders of the shield plate, thereby pushing the press-fit portions of the shield plate right in the through holes in exact linear-alignment with the through holes. Thus, a strong thrust can be transmitted to each press-fit portion without causing it to be deformed or bent.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a hard-metric (abbreviated as HM) connector of the type used in exchangers, servers or computers. It uses a press-fit type of shield plate to facilitate the mounting of the shielded connector onto a printed circuit board.

2. Related Art

Referring to FIGS. 5(A), (B) and (C) and FIG. 6, a conventional electrical connector 10 has a press-fit type of “L”-shaped shield plate 13 tentatively fastened to its body 12 by making the engagement extensions of a flat top 13 a of the shield 13 to be engaged on a front side of the connector body 12. The shield plate 13 has a vertical section 13 b extending downward via bent round portion 13 c. The rear part of the connector body 12 has its bottom raised to a level higher than the bottom of the front part, thus leaving a space to accommodate a printed circuit board 11. As seen from FIGS. 5(C) and 6, the rear part of the connector body has the male contact portions 3 b of the contact pieces 3 projecting downward from the raised bottom, and press-fit portions 13 d of the vertical section 13 b of the shield plate 13 extend parallel to the male contact portions 3 b of contact pieces 3 so that their tapered ends may be coplanar with the tapering ends of the male contact portions 3 b. The connector body 12 has female receptacles arranged in a lattice form on its front side, in which the female contact portions of the contact pieces 3 are inserted.

When the electrical connector 10 is fixed to the printed circuit board 11, an “L”-shaped pressing tool having a round comer approximately corresponding to the bent round portion 13 c of the shield plate 13 is applied to the shielded connector body, and then, a strong thrust is applied to the flat top 13 a to push the male contact portions 3 b and the press-fit portions 13 d into the though-holes of the printed circuit board 11.

Application of a several Newton-strong push to each male contact portion and press-fit portion is apt to bend some or all press-fit portions. Also disadvantageously, before applying a thrust to the connector the “L”-shaped shield plate needs to be tentatively fastened to the connector body 12 with a piece of double-sided adhesive tape. This is an elaborate, time consuming process.

One object of the present invention is to provide a shielded electrical connector which is guaranteed to be free of such defects as described above.

SUMMARY OF THE INVENTION

To attain this object an electrical connector comprising a connector body having contact pieces embedded therein and an “L”-shaped shield plate applied to the connector body with its horizontal and vertical sections lying on the top surface and rear side of the connector body respectively, the shield plate having press-fit portions formed at the lower end of the vertical section, is improved according to the present invention in that the shield plate has a plurality of thrust shoulders formed at its horizontal-to-vertical transition to push the press-fit portions.

The electrical connector can be fixed to a printed circuit board by applying a push to the thrust shoulders of the shield plate, thereby pushing the press-fit portions of the shield plate right in the through holes in exact linear-alignment with the through holes. Thus, the strong thrust can be transmitted to each press-fit portion without any possibility of causing it to be deformed or bent.

The shield plate may have engagement extensions formed ahead of its horizontal section, and engagement projections formed in its vertical section; and the connector body may have catch means formed on its front and rear sides respectively, whereby the shield plate can be attached to the connector body.

This arrangement facilitates the tentative fastening of the shield plate to the connector body without the necessity of using any adhesive agent and/or doubled-sided adhesive tape.

Other objects and advantages of the present invention will be understood from the following description of a shielded electrical connector according to one preferred embodiment of the present invention, which is shown in the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIGS. 1(A)-(C), an HM connector 1 comprises a connector body 2 having contact pieces 3 insert-molded therein and an “L”-shaped shield plate 4 applied to the connector body 2 with its horizontal and vertical sections 4 a and 4 b lying on the top surface 2 a and rear side 2 b of the connector body 2. The shield plate 4 has press-fit portions 4 d integrally connected to the lower end of the vertical section 4 b of the shield plate 4.

Referring to FIG. 4(A), the connector body 2 comprises front and rear halves integrally connected by insert molding contact pieces 3. The front half has a plurality of female receptacles 2 c made in a lattice form, and the female contact portions 3 a are inserted in the female receptacles 2 c. The rear half of the contact body 2 has the intermediate lengths of the contact pieces 3 embedded therein. The vertical extensions of the contact pieces 3 partly appear from the bottom of the rear half of the conductor body 2 to provide male contact portions 3 b. As shown in FIG. 4(A), the male contact portions 3 b are pushed in selected through holes made in the printed circuit board 11.

As shown in FIG. 2, the shield plate 4 has a plurality of thrust shoulders 4 e formed at its horizontal-to-vertical transition 4 c for use in pushing the press-fit portions 4 d in the through holes of the printed circuit board 11. Such thrust shoulders 4 e can be formed by making flattened “U”-shaped cuts in a selected linear stripe portion extending from side to side, which linear stripe portion is to be bent at right angles to form a horizontal-to-vertical transition on its rear side when bending the shield plate into its final shape. That is, as shown best in FIGS. 4(B)-4(D), each thrust shoulder 4 e is constituted by a cut-out from the vertical section 4 b and is integral and coplanar with the vertical section 4 b. A top end of each thrust shoulder 4 e is separated from the horizontal section so as to serve as a pushing location at which a pushing force can be applied in a direction along the vertical section for pushing the press-fit portions 4 d.

Referring to FIGS. 2 to 4(D) , the shield plate 4 has engagement extensions 4 f formed ahead of the top flat section (horizontal section) 4 a on its front side (FIG. 2), and engagement projections 4 g formed on the vertical section 4 b. The shield plate 4 can be fastened to the connector body 2 by allowing the engagement extensions and portions 4 f and 4 g to be caught by catch portions or recesses 2 d. Thus, a shielded electrical connector is provided.

The shielded electrical connector thus provided can be fastened to a printed circuit board 11 simply by applying a thrust to the thrust shoulders 4 e of the “L”-shaped shield 4 to push the male contact portions 3 b and the press-fit portions 4 d in the through holes of the printed circuit board 11. The thrust can be transmitted right from the thrust shoulders 4 e to the press-fit portions 4 d of the vertical section 4 b of the “L”-shaped shield 4 so that the press-fit portions 4 d may be pushed in selected through holes in the printed circuit board 11 without being deformed or bent.
